Test of Significance
1
One Sample t test
(sample size < 30 / Population SD is not known )
One Sample Z test
(sample size > = 30 OR population SD is known )
2 (unrelated)
Unpaired t test (Student's t)
(sample size < 30 )
Z test (Standard error of difference between two means)
(sample size > = 30 AND population SD is known )
2 (related or paired)
Paired t test
(sample size < 30 )
Paired Z test
(sample size > = 30 AND population SD is known )
>= 3 (unrelated)
One way ANOVA
(One independent variable or factor)
Two way ANOVA
(Two independent variables or factors)
>= 3 (unrelated)
One way ANCOVA
(One independent variable plus one continuous covariate)
